Use this API to admin-cancel a specific step. The step transitions to cancelled, no downstream edges fire from it, and a step.cancelled event is emitted.

Endpoint

POST https://api.velt.dev/v2/workflow/steps/cancel

Headers

x-velt-api-key · string · required

Your API key.

x-velt-auth-token · string · required

Your Auth Token.

Body

Params

data · object · required

Show properties

executionId · string · required

The execution containing the step.

stepId · string · required

The step to cancel.

reason · string

≤ 500 chars. Surfaced on the step.cancelled event.

actorId · string · required

1–256 chars. Identifier of the administrator initiating the cancellation. Recorded on the step.cancelled audit event.

Workspace-admin RBAC is post-GA. Today this endpoint gates on the standard x-velt-auth-token only. Until role-based access lands, restrict who can call /steps/cancel inside your own application.
